There are two types of call transfer that your system if capable of:

  1. Blind transfer:  This is where the call is directy transferred to another user without any introduction.  Following the transfer, the other phone will ring showing the callerid of the original caller.  If there is no answer, the call would go to the voicemail of the numebr the call was being transferred to.
  2. Attended transfer:  In this scenario, the user transferring the call would have the opportunity to speak to the transfer recipient before the call is transferred.  The recipient on the transferred number sees the callerid extension  number of the user transferring the call rather than the original callerid.  If the recipient is not available or does not want to take the call, the user can return to the original call.

The system is also capable of making conference calls joining multiple calls.  The 3xx series of phones is capable of conference 3 simultanous calls including the user of the phone.
